Application filed September 15, .1911. Serial No. 649,515.

To all whom it may concern:

Be it known that I, Ronmir CARR WALL, of Philadelphia, in the Stem ofPennsyl- Vania, have inventeda certain new and useful Improvement inTire-Fastening Devices, whereof the following is a specification,reference being had to the accompanying drawm IVIy invention relates tomeans for fastening pneumatic tires upon vehicle wheel rims andparticularly to a divided retaining ring flange and means for securingit upon a wheel rim,

' As hereinafter described, my invention includes a divided ring flangehaving inwardly projecting wedges at its ends, and wrench holds at itsinner circumference near said ends, fitted to a rim having a slot toreceive said wedges and fulcrum sockets affording access to said wrenchholds; a lever wrench adapted to fit in said fulcrum sockets inengagement with said wrench holds, whereby said ring may be constrictedupon said rim; and, means normally retaining said ring on said rim.

My invention includes the variousnovel features of construction andarrangement hereinafter more definitely specified.

In the drawing :Figure I is a side elevation of a wheel folly, rim andretaining ring conveniently embodying my improvement. Fig. II is asectional view taken on the line II, II, in Fig. I. Fig. III isafragmentary side elevation of a wheel rim and retaining ring embodyinga modified form of my invention. Fig. IV is a sec tional view taken onthe line IV, IV in Fig. III.

In the form of my invention shown in Figs. I and II; the metal rim 1' isfitted in concentric relation upon the wooden felly 2 to which it isconveniently secured by the screws 3. Said rim is provided with theremovable ring flange 5 which is divided as indicated at 6 in Fig. I andhas inwardly projecting wedges 7 at its ends extending in a planetransversely to its axis, with complementary recesses 8 in thecontiguous edges of saidwedges; wrench holds 10, adjoining said ends,and conveniently oppositely inclined ratchets atthe inner circumferenceof said ring. Said ring has the stud 11 rojecting radially inward@intermediate of its ends 11 fitted to the socket 12 in said rim 1, thelatter havirw a slot 14 to receive said wedges 7, and fa cram sockets 15afi'ording access to said ratchets 10. The screw 17 which extends insaid recesses 8 norinallyretains said ring on said rim by engagementwith said telly as indicated in Fig. II. Upon removing said screw 17 thering 5 may be detached from the rim 1 by springing its ends outwardlywith the lever 18 which may be conveniently engaged in the notches 20 insaid rim. To replace said ring its stud 11 may be engaged with thesocket 1.2 in said rim 1 and its ends sprung apart, with the wedges 7 inalinementwith said slot 14. Thereupon, the ring ends may be alternatelyshifted circumferentially to constrict said ring 5 upon the rim 1 andseat said wedges in said slot, by engagement of said lever 18 with theratchets 10 through the fulcrum sockets 15. Itmay be observed that whenthe ends of said ring 5 are shifted circumferentially as above describedand the wedges 7 pressed radially inward to the position shown in Fig.I, said wedges respectively bear upon the opposite ends of said slot 14in the rim and thus prevent retraction of the ring from its constrictedpositionto which it has been shifted by the lever 18; the angle of saidwedges in contact with said rim being such that it is necessary to movethem radially outward to release them. However, the screw 17 preventstheir accidental displacement.

In the form of my invention shown in Figs. III and IV, the metal rim 21is provided with the removable ring flange 22'- which is divided asindicated at 23 in Fig. III and has inwardly projecting wedges 25 at itsends extending in a plane transversely to its axis, with complementaryrecesses or openings 26 in alineinent in said wedges; the latter beingfitted in the slot 27 in said rim 21 so as to present said openingswithin the latter as indicated in Fig. IV. Said ring 22 is normallyretained on said rim by the cotter pin 28, one limb of which extendsthrough said openings 26; the opposite end of said pin being bent asindicated at 30, forming a spring catch to engage the edge of thecontiguous wedge 25 and prevent ,accidental removal of said cotter pin.Said rim 21 is not provided with notches to receive the lever 18 likethe notches 20 shown inFig. I; but, said ring 22 is provided withnotches 31 to engage said lever'whereby its ends may be sprung outwardlyto remove it from said rim 21. Said ring 22 is also convenientlyprovided with wrench holds 32 similar to'the wrench holds 10 in. thering 5, and, like the latter accessible for engagement with the lever.18 throu 'h fulcrum sockets 33 in said rim 21. Sai' ring 22 is alsoconveniently provided with the stud 3i projecting radially inwardintermediate of its ends and fitted to the socket 35 in said clai 1. Atire fastening device including a divided ring flange having inwardlyprojec ing wedges at its ends extending in a plane transversely to itsaxis, with complementary openings in the contiguous edges of saidwedges, oppositely inclined ratchets at the inner circumference of saidring adjoining its ends, and a stud on said ring projecting radiallyinward intermediate of its ends; a rim having a slot to receive saidwedges, a socket for said. stud, and fulcrum sockets affording access tosaid ratchets; a folly in concentric relation with said rim within thelatter; and,a cotter pin extending in said complementary openings,normally retaining said ring on said rim; said pin having means toresiliently engage said ring includ ing an inwardly turned endoverlapping the contiguous wedge.
